In the Charolais ridge in the northeastern part of the Central Massif (France) two granites can be distinguished. The Vauzelles granite to the south, is subalkaline, medium-grained, slightly porphyritic, and poor in inclusions. The Mary granite to the north is a coarse-grained monzonitic porphyry, containing green hornblende, and rich in inclusions. Identical granophyres are associated with both granites, but in differing modes of occurrence. This is ascribed to the difference in depth of the granites, the Vauzelles being deeper. The age of the granites is Visean (Carboniferous).
